## Overview:

We took a look at the Geometry section of the

*n*spire calculator. We went from a circle to a graph through various techniques of the*n*spire. The technology is amazing in the fact that this can all be done on one piece of technology is something unheard of.As shown above, there were 3 pages to this document.
First, we had to create the circle and find the radius, area, and circumference.
Then, we input this data into a spreadsheet with the correct variables from the circle.
Lastly, we graphed the radius vs. the area of the circle to create a function with various points.

## 10C

This corresponds to the 10C

__Relations and Functions__curriculum specifically number 7. Students need to determine the equation of a graph given a graph, points, an slope to solve problems. Students are required to: - Determine the slope and y-intercept of a given linear relation from its graph, and write the equation in the form y = mx + b. - Write the equation of a linear relation, given its slope and the coordinates of a point on the line, and explain the reasoning. -**Write the equation of a linear relation, given the coordinates of two points on the line, and explain the reasoning.**- Write the equation of a linear relation, given the coordinates of a point on the line and the equation of a parallel or perpendicular line, and explain the reasoning. -**Graph linear data generated from a context, and write the equation of the resulting line.**- Solve a problem, using the equation of a linear relation.## Sample Questions:

__Grade 10:__Get the students to build a shape in the geometry section and get them to go through the same process as above to graph a function.

## Conclusion

I like this problem, but sometimes the technology with the

*n*spire can be a bit touchy. Sometimes the center button won't work and it gets confusing. The concepts related to it though is extremely helpful and important. I liked the flow from the geometry to the spreadsheet to the graph, it was seamless and efficient.
